Abstract
There is provided an air flow deflector apparatus for a thrust reverser system of an engine of an air vehicle. The air flow deflector apparatus is movable between a stowed non-reversing position and a deployed thrust reversing position, to deflect an air flow out of the engine, and to provide an effective reverse thrust for the thrust reverser system. There is further provided an air flow deflector assembly for a structure. The air flow deflector assembly has the air flow deflector apparatus, an extender member, and a recessed housing disposed in the structure. The air flow deflector assembly has an air flow deflector actuator that moves the air flow deflector apparatus between a stowed position and a deployed position adjacent to a reverse efflux air flow exit portion of the structure. The air flow deflector assembly deflects a reverse efflux air flow away from being re-ingested into the structure.
